Vacuum Cleaning System for Sheet Material Cutting Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet material cutting machines face inefficiencies due to debris accumulation between bristles, which hinders cutting tool operation and airflow, requiring manual cleaning or offline cleaning systems that are time-consuming and not suitable for all machine types, especially for achieving a 'zero buffer' cutting process.
Innovation Solution
A vacuum cleaning system integrated into the cutting tool, such as a hollow drill or press foot, that removes debris during the cutting process using vacuum pressure, allowing continuous operation without interrupting the cutting process and maintaining precise vacuum pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vacuum cleaning system is integrated into the cutting tool to remove debris during cutting, then productivity and manufacturing precision are improved, but device complexity increases
Solution Approach 1:
The vacuum cleaning system is merged with the cutting tool assembly, where the vacuum source, collection container, and debris removal mechanism are integrated into the existing cutting tool structure. This allows debris removal to occur during the cutting operation without requiring separate cleaning equipment or interrupting the cutting process, thereby improving productivity while managing device complexity through unified design.
2Manufacturing precision
If debris is removed continuously during cutting, then manufacturing precision is improved, but use of energy increases
Solution Approach 1:
The vacuum cleaning system operates periodically rather than continuously throughout the entire cutting process. The system activates to remove debris at specific intervals or at critical points during cutting, then pauses while maintaining sufficient vacuum pressure. This periodic operation reduces overall energy consumption compared to continuous vacuum operation, while still achieving the necessary debris removal to maintain manufacturing precision.
3Ease of operation
If the vacuum cleaning system is integrated into the cutting tool, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The vacuum cleaning system is designed to operate automatically during the cutting process without requiring manual intervention. The system self-activates when debris accumulation is detected or at predetermined intervals, performs debris removal autonomously, and manages its own operation including vacuum pressure regulation and collection container management. This self-service capability improves ease of operation by eliminating the need for operators to manually clean debris during cutting, while the automation is achieved through integration with the existing cutting tool control systems.

AI summary
A sheet material cutting machine (10) includes a bristle bed (14) with generally vertically extending bristles having free ends defining a support surface for supporting sheet material to be cut and a carriage (32) movable over the bristle bed (14) and carrying at least one cutting tool (61 ) to selectively cut the sheet material. A vacuum cleaning system (28) provides vacuum at the carriage (32) to remove cutting debris as the cutting tool (61 ) is cutting the sheet material. Illustrated embodiments include providing the vacuum through a passage in the cutting tool (61) and providing the vacuum through a cavity in a presser foot (64).
